    The product of the length of the magnet and its pole strength is called the moment of a magnet or Magnetic moment. If 'm' is the pole strength and 2l is the length of the magnet then, the moment of the magnet or Magnetic moment is given by. M =m xx 2l . Also, Magnetic moment is a vector quantity, with its direction from south pole to north pole along its axial line. If a bar magnet of magnetic moment 80 units be cut into two halves of equal lengths the magnetic moment of each half will be
